Congrats! And let me be the first to congratulate the tike on choice of parents. Though perhaps she or he is destined to be the first kid in history to have a father complain that it is far too large as an infant for good photos.

They can do that now! 3-d ultrasounds are pretty much focus stacking for ultrasound. We saw a couple on our 3rd kid as routine imagery (as well as fetal MRI, but that wasn’t so routine). The artifacts are a bit high so don’t freak out a weird protrusions where the don’t belong!

What, no points for identifying genus and species? Darn. Not being an entomologist, yet a regular visitor to your blog and admirer of your work, there I was hoping that for once I could confidently answer one of your weekly mystery challenges and earn some points!

Congrats! My guess is XY. And as a father of a toddler (and of one more on the way), I can only say good luck keeping those small, sweet, inquisitive, active, and very very fast hands off your expensive photographic equipment in a few years’ time…
